609-2RS Deep Groove Ball Bearings, ID 9mm x OD 24mm x Width 7mm Miniature Bearings, Double Rubber Sealed Ball Bearing Pre-Lubricated Chrome Steel Z2 Lever 10pcs

HiPicco 605-2RS Deep Groove Ball Bearings, ID 5mm x OD 14mm x Width 5mm Miniature Bearings, Double ....I have a 3D printer and print all sorts of different things. I have seen a lot of designs for things that require bearings of some form or another but never sure what bearings I should get. Having seen these, I thought I would give them a try, the hard part was deciding on the size as they come in lots of different inner and outer sizes.I decided on 5x14x5, so that is 5mm inside and 14mm outside diameters and 5mm thick with each bearing weighing about 3.6g They were supplied in a soft plastic tube and each bearing is very lightly oiled. I don’t have any experience with these sorts of bearings, but they appear to be well made, they feel smooth, and they do not spin loosely.The are ideal for small projects and I looking forward to putting them to use.

I got these for various builds i do with 3d printing. Gave them a go and the measurements are spot on, the come in a nice plastic tube and rotate freely and very well. Would definately get these again!

These bearings came well packaged, the operation is very smooth. The measurements are accurate as per manufacturer's spec sheet. The workmanship is very good, smooth edges and perfect fit! The rollers are sealed for long lasting. Very well made and good product.

I use this bearing size in various hobbyist applications, primarily related to 3D printers or 3D printing projects, so I've purchased these from multiple manufacturers in the past. These bearings outperform the others I've used because they are not excessively coated in oil and are entirely free from any corrosion. They are lightly oiled and completely corrosion-free. In terms of dimensional accuracy, they typically fall within a range of three one-hundredths of a millimeter, which I consider well within the margin of error for my measuring process. All in all, I find these bearings to be a great value, and I would definitely buy them again when I need bearings.

These 608-2RS bearings come packed in a plastic storage tube.The bearings are dimensionally consistant and are well machined to within normal tolerances.The finish is uniform and without blemishes or burrs. The bearings are very lightly oiled and have good quality rubbers seals on both sides of the bearing race. The bearing seals do not weep with operation. Mechanical operation is smooth and quiet.These bearing work extremely will compare to other similar products.

These are already well greased for skateboards or other equipment that takes 80+ lb loads. They move smoothly and feel solid.
